About NHA

Norm Hill Aviation Inc. (NHA) was founded in April 1996 by Norman A. Hill as a Sole Proprietorship. The Company was later incorporated as a Limited Liability Company in April of 2009. NHA specializes in supplying parts, maintenance, and support to the Gulfstream Business Jet community worldwide. The Gulfstream Aircraft is the number one corporate business jet in the world. NHA currently has 11 employees and expects to continue our present growth as we add services and expands our facilities.

NHA supports Gulfstream owners and operators with a wide range of maintenance, parts, and services and are well respected within the Gulfstream community. In 2011 NHA moved to our present facilities, a 4 hanger complex, in California City, CA. This has allowed NHA to offer expanded services to our customer base and enhance our value to our existing and potential Gulfstream customers. NHA expects to purchase and retire three to four additional Gulfstream aircraft per year, thereby ensuring that a steady stream of affordable parts is available to our customers.

Although Grumman American/Gulfstream has historically done a good job supporting their airplanes, parts are getting more and more expensive, with longer lead times for shipment. Some parts are now on a build-to-order basis at astronomical prices and in most cases with extremely long lead times for manufacture. This leaves an aging fleet of approximately 950 Gulfstream ll, lll, and lV “Legacy” aircraft hungry for affordable parts and services which are receiving minimal support from Gulfstream. NHA currently co-owns 19 Gulfstream aircraft which are being used for the express purpose of supplying parts to the owners of the 450 legacy Gulfstream II/III aircraft.
